Abstract:

The Naval Ocean Systems Center NOSC has conducted the third in a series of evaluations of English text analysis systems. These evaluations are intended to advance our understanding of the merits of current text analysis techniques, as applied to the performance of a realistic information extraction task. The latest one is also intended to provide insight into information retrieval technology document retrieval and categorization used instead of or in concert with language understanding technology. The inputs to the analysisextraction process consist of naturally-occurring texts that were obtained in the form of electronic messages. The outputs of the process are a set of templates or semantic frames resembling the contents of a partially formatted database. The premise on which these evaluations are based is that task-oriented tests enable straightforward comparisons among systems and provide useful quantitative data on the state of the art in text understanding. The tests are designed to treat the systems under evaluation as black boxes and to point up system performance on discrete aspects of the task as well as on the task overall. These quantitative data can be interpreted in light of information known about each systems text analysis techniques in order to yield qualitative insights into the relative validity of those techniques as applied to the general problem of information extraction. The process of conducting these evaluations has presented great opportunities for examining and improving on the evaluation methodology itself.
